We used to have one at home. It's like a clam shell -- the roll sits in the bottom half, the hinged top half closes on top, and the paper is threaded through a wide gap.
It was popular in former Soviet territories. My guess is that many households only had poorly-built outhouses and no reliable supply of toilet paper, and this design protected the roll from water damage.
That's awesome dude, nice work! I wish I were this good in blender. I have to use CAD to make my models and then export them to the scene in blender. It's an annoying workflow but I'm just not good at "traditional" modeling in blender
There are plastic containers similar to box tissue but are round with a hole in the middle of the lid. Then you pull the toilet paper from the center of the roll.
